ADELAIDE Oval's membership phone lines and website have crashed due to demand for Ultimate Memberships, after registrations opened today.

The South Australian Cricket Association has asked for patience, tweeting that ticketing company Ticketek is experiencing heavy traffic.

When the lines opened this morning, Ticketek was receiving 150 calls a minute.

The registration period for Ultimate Memberships opened at 9am this morning and will close at 5pm on November 27.

At the conclusion of the registration period, SACA's allocation of 6100 Ultimate Memberships will be offered on a first in, first served basis to those members who have registered and paid the $75 registration fee.

The SANFL's allocation of 6100 Ultimate Memberships will be offered to Foundation Members, then AAMI Stadium Premier Members in 2012 and 2013, before being offered to Crows and Power members and those on membership waiting lists.
